无法访问Dockerfile中ADD / chown / chmod创建的docker中的自己的目录(can't access own directory in docker created by ADD/chown/chmod in Dockerfile)

我尝试将ssh私钥添加到Dockerfile的docker构建中，它看起来有线，我无法访问它，即使它看起来我有完全权限

Docker Version: 1.0.0 Docker host: ubuntu 14.04

这是Dockerfile

FROM ubuntu:latest ENV HOME /home/larry RUN useradd larry && echo 'larry:docker' | chpasswd RUN echo "larry ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers # arrange ssh key ADD larry.id_rsa $HOME/.ssh/id_rsa RUN \ chmod 700 $HOME/.ssh &&\ chmod 600 $HOME/.ssh/id_rsa RUN chown -R larry:larry $HOME

在我构建图像并运行到容器和su给用户larry ，我得到了

$ id uid=1000(larry) gid=1000(larry) groups=1000(larry) $ ls -al total 12 drwxr-xr-x 5 larry larry 4096 Jun 21 01:29 . drwxr-xr-x 5 root root 4096 Jun 21 01:29 .. drwx------ 2 larry larry 4096 Jun 21 01:29 .ssh $ cd .ssh -su: cd: .ssh: Permission denied

也许我错过了码头工人的一些基本概念？ 从正常的unix用户角度来看，只是连线。

我把它放在github以及https://github.com/dotcloud/docker/issues/1295#issuecomment-46700769

I try to add ssh private key into docker building from Dockerfile, it looks wired that I can't access it even it looks like I have full permission

Docker Version: 1.0.0 Docker host: ubuntu 14.04

Here is the Dockerfile

FROM ubuntu:latest ENV HOME /home/larry RUN useradd larry && echo 'larry:docker' | chpasswd RUN echo "larry ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers # arrange ssh key ADD larry.id_rsa $HOME/.ssh/id_rsa RUN \ chmod 700 $HOME/.ssh &&\ chmod 600 $HOME/.ssh/id_rsa RUN chown -R larry:larry $HOME

After I build the image and run into container and su to user larry, I got

$ id uid=1000(larry) gid=1000(larry) groups=1000(larry) $ ls -al total 12 drwxr-xr-x 5 larry larry 4096 Jun 21 01:29 . drwxr-xr-x 5 root root 4096 Jun 21 01:29 .. drwx------ 2 larry larry 4096 Jun 21 01:29 .ssh $ cd .ssh -su: cd: .ssh: Permission denied

Maybe I missed some basic concept in docker ? Just wired from normal unix user point of view.

I put this in github as well https://github.com/dotcloud/docker/issues/1295#issuecomment-46700769

最满意答案

你刚刚遇到bug ＃6047 ，它基本上说在chmod之后运行时它们是chown问题。

以下Dockerfile将起作用：

FROM ubuntu:latest ENV HOME /home/larry RUN useradd larry && echo 'larry:docker' | chpasswd RUN echo "larry ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers # arrange ssh key ADD larry.id_rsa $HOME/.ssh/id_rsa RUN chown -R larry:larry $HOME RUN \ chmod 700 $HOME/.ssh &&\ chmod 600 $HOME/.ssh/id_rsa

You just met bug #6047 which basically says they are issues with chown when run after chmod.

The following Dockerfile will work:

FROM ubuntu:latest ENV HOME /home/larry RUN useradd larry && echo 'larry:docker' | chpasswd RUN echo "larry ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers # arrange ssh key ADD larry.id_rsa $HOME/.ssh/id_rsa RUN chown -R larry:larry $HOME RUN \ chmod 700 $HOME/.ssh &&\ chmod 600 $HOME/.ssh/id_rsa
